220-0002 - Miller Smith 220 Series Silverline Two-Stage CO2 Regulator 15 PSI

Precision Analytical Control with Miller Smith Silverline

The Miller Smith 220-00-02 Silverline High Purity Analytical Two Stage Regulator is engineered for the most demanding laboratory and industrial applications where gas purity and pressure stability are paramount. As part of the renowned Silverline 220 Series, this regulator is specifically configured for Carbon Dioxide (CGA 320) service, delivering a precise outlet pressure range of up to 15 PSI. The core of its performance lies in its two-stage design, which effectively reduces cylinder pressure in two steps. This architecture ensures that the delivery pressure remains constant even as the cylinder pressure drops from full to nearly empty, a critical requirement for analytical instruments that are sensitive to pressure fluctuations.

Material selection is central to the 220-00-02's high-purity credentials. The regulator features a stainless steel diaphragm that not only provides sensitive pressure control but also eliminates the risk of elastomeric outgassing, preserving the integrity of the gas stream. This is complemented by a filtered seat mechanism that prevents particulate contamination, further enhancing purity and extending the service life of the unit. The body and bonnet are constructed from rugged brass bar stock and are fully plated, offering superior protection against environmental corrosion and wear. This robust construction ensures reliability in both laboratory environments and harsher industrial settings.

Safety and operational versatility are also key features. The regulator includes a built-in capturable preset safety relief valve, which protects downstream equipment and the regulator itself from over-pressurization events. Furthermore, the design is robust enough to withstand vacuums generated during purging operations, making it suitable for complex gas management systems. Large, 2-1/2 inch single-scale gauges provide clear, immediate readouts of both inlet and delivery pressures, allowing operators to monitor system status with ease. Whether used for gas chromatography, flame ionization, or other carrier gas applications, the Miller Smith 220-00-02 delivers the consistent, high-purity performance required for accurate analytical results.
